Australia-Spain tax treaty and CGT on Australian property
Australia and Spain have a Double Tax Agreement (DTA) in place. If you become a tax resident of Spain (typically by residing more than 183 days per year), your worldwide income, including Capital Gains Tax (CGT) from Australian property, will generally be reportable in Spain. However, under the DTA, CGT on Australian real estate is taxed in Australia first, and you can claim a credit in Spain for the tax paid in Australia, mitigating double taxation. Specific advice from a tax professional is recommended due to individual circumstances.
